Application:
Square hole drills are mainly used for woodworking.
The reason is that there is an impact body, which is used for drilling steel, iron, and materials, and has high requirements on tool strength.
The specific principle is as follows: square hole drill bit, belonging to a hardware tool, mainly composed of an inner rotary impact body and an outer impact body.
The existing drills can only process circular holes and cannot machine square holes.
If square holes are to be machined, the holes must be machined with a round hole drill or a cutting machine, and then manually cut.
The utility model uses the inner rotating body to drill a round hole, and uses the electric hammer to transmit the impact force to the outer impact body, and breaks the material between the round hole and the square head wall, and is processed into a square hole at one time, and the dust can be broken. Discharge from the slag discharge pipe.
Use square hole drills of different specifications and select square holes with appropriate power to make the square holes that meet the requirements.
It can reduce the labor intensity of construction workers, speed up construction, reduce construction costs, and is suitable for construction, installation, decoration and decoration industries.
